Orky

This is Orky, a male killer whale.
He is seen breaching in his pool at Marineland of the Pacific, California, USA.
When this picture was taken, he shared the pool with common dolphins. Later, he got other killer whales for companions.

The picture dates back to the early 1970's.

Chimo

This is Chimo, the white killer whale.
This transient killer whale suffered from a rare condition called Chediak Higashi-syndrome.
The condition caused partial albinism, explaining why her skin is so lightly pigmented.
The following page at Orcahome.de holds more photographs of Chimo, at the park that she was held at: Sealand of the Pacific in Victoria, Canada.

Transient killer whales are mammal-hunting predators, in contrast to resident killer whales, that feed on fish (salmon, herring, etc).
Both varieties inhabit overlapping areas, but don't interbreed.


Physical differences are used to tell both varieties apart:

-Transient killer whales have pointed dorsal fins. The grey saddle patch is uniformly grey.
-Resident killer whales' dorsal fins are generally curved and have rounded tops. Their saddle patches are often 'open', with lighter areas surrounding darker areas.

Windsor whale

This is Winston, a resident male killer whale who lived at the Windsor Safari Park in Great Britain for a long time.
The picture was taken prior to his big move to SeaWorld of California in the United States.
